Forget gingerbread houses, there’s an actual gingerbread city at Westfield London. Created by the Museum of Architecture, this is seventh year of the project and this time, the theme for the exhibition is ‘Water in Cities’. The aim us to explore how cities could be designed to be more water resilient (something that’s becoming more and more pressing each year), only doing it through the mediums of biscuits, sweets, cakes, and icing. Not only is this a sweet way to help get the public excited about architecture and innovative, sustainable design, a little holiday cheer never hurt anybody.
